JP6034166B2 - Selective storage device for screens displayed on business terminals - Google Patents

Description

  The present invention relates to a selective storage device that selects and stores a part of a series of screens displayed on a business terminal.

  For example, in a monitoring / control system for a communication system, a maintenance person performs various settings for the communication system using a terminal such as a computer, and monitors a failure that has occurred in the communication system using these terminals and performs control according to the failure. Run.

  Here, for example, the control performed on the communication device of the communication system may cause the communication device to behave unexpectedly, and this unexpected behavior may cause a failure of the communication system. In such a case, in order to analyze the cause, in a monitoring / control terminal (hereinafter referred to as a business terminal), what kind of control is performed on each communication device in the past, It is necessary to confirm whether or not an abnormal behavior has occurred due to what kind of control performed when the communication apparatus is in any state. Each communication device in the communication system has a function of recording a log when receiving a control signal from a business terminal or when an abnormality is detected in a signal transmitted / received by the own device. It is recorded in communication devices distributed in the communication system, and much time is required to collect and analyze these logs from each device in the communication system.

  Here, for example, consider recording with a camera or the like provided separately with a screen displayed on the business terminal. By recording the screen, even if an unexpected situation occurs, if you examine the captured screen in chronological order, you can grasp the control contents until the unexpected situation and the state of the communication system at that time It becomes possible to do. However, unexpected situations rarely occur, and extracting and analyzing necessary screens from long-term recordings is a very time-consuming operation.

  Here, Patent Documents 1 to 3 disclose a configuration in which the importance is determined based on video characteristic information, audio information, or caption text information registered in advance for a recorded moving image, and a summary of an important part is created. ing.

  However, video characteristics information, audio information, or subtitle text information for selecting a screen related to the cause of an abnormal event is set for a moving image obtained by capturing screens of various business terminals such as monitoring / control terminals. It is not easy.

  The present invention provides a selective storage device that selects and stores a part of a series of screens displayed on a business terminal for later analysis.

According to one aspect of the present invention, the selective storage device includes a monitoring unit that monitors whether or not a predetermined operation has been performed based on operation information indicating an operation performed on the input unit of the business terminal; A determination unit that determines whether the screen displayed on the display unit of the business terminal when the operation is performed is a reference screen, and the screen displayed on the display unit has changed by a threshold or more compared to the reference screen And a storage unit that stores the screen displayed on the display unit when it is determined that the determination unit has changed more than a threshold value within a predetermined time after the predetermined operation is performed. It shall be the feature.

  Of the series of screens displayed on the business terminal, it is possible to select and save some screens that are likely to be required for later analysis.

1 is an exemplary configuration diagram of a selective storage device according to an embodiment. FIG. The figure which shows the example of mounting of the selection preservation | save apparatus by one Embodiment. The flowchart of the selection preservation | save process by one Embodiment.

  Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. In the following drawings, components that are not necessary for the description of the embodiments are omitted from the drawings. In the following embodiment, the business terminal is a control / monitoring terminal of a communication system, and a screen that is considered necessary for analysis of a failure or the like is selected from a series of screens displayed on the terminal and saved. Will be described as an example. However, the present invention is not limited to control and monitoring of a communication system, and is necessary for analyzing the cause of a problem from a screen displayed on a terminal of various business systems using a power, transportation system, or communication network. It can be applied to select and save the screen that seems to be.

  A schematic configuration of the selective storage device 100 according to the present embodiment is shown in FIG. The trigger monitoring unit 11 of the selective storage device 100 is an input unit to the business terminal, for example, a specific operation on a mouse or a keyboard is used as a trigger, and the occurrence of this trigger is monitored. The operation to be a trigger is determined in advance based on the operation target of the business terminal, for example, the control of the communication device in the communication system and the content of the operation performed on the mouse or keyboard that is the input unit of the business terminal for performing the control. And stored in the trigger monitoring unit 11. As an example, a press of an enter key, a space key, a left click of a mouse, or the like can be used as a trigger. Note that a plurality of keys pressed simultaneously can be used as a trigger.

  In the present embodiment, triggers are classified into two types, high priority and low priority. The high priority and the low priority are determined in advance according to the trigger and the control content by the trigger. For example, it is assumed that the Enter key means confirmation of a command input before that and transmission to the communication device. The occurrence of an abnormal event is likely to occur when a certain command is issued to the communication apparatus. In this case, for example, the Enter key is given high priority. On the other hand, the space key is used to postpone a response that cannot be displayed on the display unit (display) of the business terminal from the communication device in response to a command already transmitted to the communication device. . In this case, since the probability that the pressing of the space key itself causes an abnormal event is low, the space key is given low priority.

  When the trigger generation unit 11 confirms the occurrence of a high-priority trigger, the capture unit 13 acquires the screen displayed on the display unit of the business terminal at that time and stores it in the storage unit 14. When the trigger generation unit 11 confirms the occurrence of the trigger, the determination unit 12 uses the screen displayed on the display unit of the business terminal when the trigger is generated regardless of the priority (hereinafter referred to as a reference screen). And the rate of change of the current screen from the reference screen is monitored for a predetermined time. When the change in the screen is equal to or greater than the threshold, the determination unit 12 acquires the screen when the threshold is equal to or greater than the threshold and stores the screen in the storage unit 14. The screen change rate is the rate of the number of pixels whose value has changed. For example, when the number of pixels in the display unit is N and the pixel whose value has changed from the reference screen in the current screen is K, the rate of change is (K × 100 / N)%. The selective storage device 100 repeats the above process while operating. Therefore, when a high priority trigger occurs, the screen when the trigger occurs is always saved. In addition, regardless of the priority, when the content of the screen changes more than a threshold value within a predetermined time from the occurrence of the trigger, the screen at that time is saved. On the other hand, even if a trigger occurs, the screen is not saved if the change in the screen within a predetermined time is less than the threshold.

  When an abnormal state occurs, normally, the content displayed on the display unit of the business terminal changes greatly. Therefore, the abnormal state can be easily analyzed by acquiring the screen after the change. For a high-priority trigger that is likely to cause an abnormal state, the screen when the trigger occurs is always saved. With this configuration, an abnormal state can be easily analyzed.

  FIG. 2 is an example of an implementation form of the selective storage device 100 according to the present embodiment. As shown in FIG. 2A, the selective storage device 100 can be mounted on the business terminal 1. More specifically, the business terminal 1 is usually a computer, and the selective storage device 100 can be mounted on the same computer as the business terminal 1 by a program executed by the computer. Further, as shown in FIG. 2B, the selective storage device 100 can be implemented as a device different from the business terminal 1. In this case, the selective storage device 100 receives operation information and screen information from the business terminal 1. The operation information is information related to the operation content of a keyboard, a mouse, and the like, and the screen information is information corresponding to the screen displayed on the display unit of the business terminal 1. In any form, the selective storage device 100 can be realized by a program that operates as each functional block shown in FIG.

  FIG. 3 is a flowchart illustrating processing executed by the selective storage device 100 according to the present embodiment. The trigger generator 11 monitors the generation of a trigger in S10. When the trigger is generated, the trigger generation unit 11 determines the priority in S11. When the priority is “high”, the capture unit 13 saves the screen when the trigger is generated. Regardless of the priority of the trigger, in S13, the determination unit 12 determines whether the rate of change of the screen from the screen when the trigger occurs is equal to or greater than the threshold. When it is less than the threshold value, the determination unit 12 determines whether or not the predetermined time has elapsed in S14, and repeats the processes of S13 and S14 until the predetermined time has elapsed. The selective storage device 100 repeats the process from S10 when a predetermined time has elapsed without the screen change exceeding the threshold value. On the other hand, when the change in the screen becomes equal to or greater than the threshold value within the predetermined time, the capture unit 13 stores the screen at that time in S15.

  In the above embodiment, the trigger is divided into high priority and low priority. However, it is possible to adopt a form in which priority is not provided. In this case, the screen when the trigger is generated can be configured to always store in the storage unit 14 or not to store.
